Thank you for your response @JoachimKurz, in the lane App Lifecycle, there is no data. I only see the Lifecycle selecting the main process.

I have the same problem but adding the code to remove SharedWorkers is working fine.

After some time I see the solution in Stack overflow. For some reason I have this code in a swift file: extension UILabel { override open func draw(rect: CGRect) {} override open var intrinsicContentSize: CGSize {} } That was the problem, I got rid off and everything works perfect!
